A diamine of formula (I) is described, in which A is hydrogen or a saturated or unsaturated C1-C20 alkyl group or an aryl group; B is a substituted or unsubstituted C1-C20 alkyl, cycloalkyl, alkaryl, alkaryl or aryl group or an alkylamino group and at least one of X1, X2, Y1, Y2 or Z is a C1-C10 alkyl, cycloalkyl, alkaryl, aralkyl or alkoxy substituting group. The chiral diamine may be used to prepare catalysts suitable for use in transfer hydrogenation reactions.
L~invention décrit une diamine de formule (I), dans laquelle A est l~hydrogène, un groupe alkyle saturé ou insaturé en C1 à C20 ou un groupe aryle ; B est un groupe alkyle, cycloalkyle, alkaryle, aralkyle ou aryle substitué ou non substitué en C1 à C20 ou un groupe alkylamino, et au moins l~un de X1, X2, Y1, Y2 ou Z est un groupe substituant alkyle, cycloalkyle, alkaryle, aralkyle ou alcoxy en C1 à C10. La diamine chirale peut servir à préparer des catalyseurs utilisables lors des réactions d~hydrogénation par transfert.
